      Calculations:

      The concentration of CO2 in the atmosphere was 295 PPM in 1900. It is
      now about 275 PPM.

      CO2 has an average lifetime of 100 - 120 years in the atmosphere.

      1 PPM of CO2 in atmosphere = 2.13 Gt (billions of tons) of carbon.

      375 PPM - 295 PPM = 80 PPM. 80 X 2.13 billion tons = 170.4 billion tons.


      Conclusion: There are 170.4 billion more tons of CO2 in the atmosphere
      now than in 1900.
